Hey, @719media, they kind of have an example at the redirect-based-on-country folder.

I did a quick rewrite, and I assume this is what you are looking for?

Please do verify the output of the host before deploying this to production to be sure you get the correct value.

function handler(event) {
    var host = event.request.headers.host.value;

    if (host !== 'example.com') {
        return event.request;
    }

    return {
        statusCode: 301,
        headers: { 
            location: { 
                value: 'https://www.example.com' 
            } 
        }
    };
}

I can create a PR for an example folder if that is something people find useful.

Cheers 🥂

Ya, that's more or less what I came up with. I was just looking for the example's presence from library author as proof that this should be done at this (the cloudfront function) level (vs. on the Origin Request of lambda@edge for caching purposes). Best practices and all.

Thanks for the response!
